Overhead costs come in two different forms: fixed and variable. The overhead rate is the cost, divided by the number of items produced or units of service sold. Fixed overhead costs are the same regardless of how productive the business is. Variable rates refer to costs that rise as productivity rises.
Fixed costs, indirect costs or overhead costs are those costs that are not dependent on the level of production. Either business manufactures 10,000 units of goods or 50,000 units of goods, it remains unchanged. Instead of volume related, this cost is time related that mean it changes according to time.
